+#   1. `vllm.config.model.ModelConfig._verify_quantization`
+#    Why:
+#       MiniMax-M2 fp8 checkpoints on NPU may fail upstream quantization validation.
+#       vllm-ascend needs to disable fp8 quantization and load bf16 dequantized
+#       weights in worker-side patches instead.
+#    How：
+#       Monkey-patch `_verify_quantization` and intercept platform quantization
+#       verification to force `cfg.quantization=None` for MiniMax-M2 fp8 on NPU.
+#    Related PR (if no, explain why):
+#       No, upstream behavior differs across versions and needs discussion.
+#    Future Plan:
+#       Remove this patch once upstream supports MiniMax-M2 fp8 on NPU or provides
+#       a backend-safe validation / override mechanism.
+#
+#   2. `vllm.config.model.ModelConfig._verify_cuda_graph`
+#    Why:
+#       For MiniMax-M2 on NPU with ACL graph capture enabled, HCCL op expansion
+#       mode affects graph shape coverage. Users may forget to set it.
+#    How：
+#       If user doesn't set it, set `HCCL_OP_EXPANSION_MODE=AIV` for this model
+#       and log a warning when a different value is detected.
+#    Related PR (if no, explain why):
+#       No, this is an environment-specific tuning knob.

+#    How：

+#       Remove this patch if upstream implements kv-head-aware norm sharding.

+#   3. `vllm.model_executor.models.minimax_m2.MiniMaxM2Model.load_weights`
+#    Why:
+#       MiniMax-M2 fp8 checkpoints may store fp8 weights with per-block inverse
+#       scales. On NPU we load bf16 weights by dequantizing at load time.
+#    How：
+#       Inject fp8 dequant helpers and wrap `load_weights` to convert fp8 weight +
+#       `weight_scale_inv` pairs into bf16 blocks before delegating to upstream.
+#    Related PR (if no, explain why):
+#       No, fp8 load format and backend constraints are model/backend specific.

+#       Remove this patch when upstream supports MiniMax-M2 fp8 loading on NPU.

+#      `vllm.model_executor.layers.mamba.linear_attn.MiniMaxText01RMSNormTP.weight_loader`
+#    Why:
+#       MiniMax-M2 linear attention RMSNorm needs weight sharding that can follow
+#       TP layout (and sometimes kv-head replication) on NPU.
+#    How：
+#       Override `__init__` to parameterize weight shard world/rank and install a
+#       sharded `weight_loader` implementation.
+#    Related PR (if no, explain why):

+#      (or older `_normalize_qk`)
+#    Why:
+#       q/k norm for linear attention is performance-sensitive. On NPU, a fused
+#       rms_norm kernel is faster and TP needs a global rstd correction.
+#    How：
+#       Replace q/k normalization with NPU rms_norm fast path and TP-global rstd
+#       correction; fall back to upstream implementation on non-NPU.
+#    Related PR (if no, explain why):
